The ex Jesuits' College (in Italian Collegio dei Gesuiti[1]) is a building in the town centre of Alcamo (in the province of Trapani).

Its construction started in 1652, on a project by Dazio Agliata (thanks to the donation by the Jesuit Vincenzo Abbati), in order to promote the diffusion of the Christian faith, but it has never been completed.

[1] The only original document about this project was found at the National Library of Paris: in the planimetry there were foreseen four sides with an inner court, the terrace covering the colonnade which was to be built on the ground floor surrounded by the wall of the attic.

Originally the colonnade of the College had four arches; only three remain now as the one which connected the arcade to the Church of Jesus (in Italian chiesa del Collegio dei Gesuiti), was demolished.

In recent times it has been restored for seven years[2] and today it is the representative house of the town, of the Museum of Contemporary Art of Alcamo[2] and of the Civic Library "Sebastiano Bagolino",[1] which hosts rare incunabula and sixteenth-century editions.
